No. 926,85 1 Specification of Letters Patent. Patented July 6, 1909.

Application filed August 1907. Serial No. 388,573.

To a who) it may concern:

Be it known that. I, ERNEST O. CART- wsronr, a citizen of the UnitedStates, re siding at Springfield, in the county of Clark and State ofOhio, have invented certain new and useful l mprovenwnts inPrinting-Presses, of which the iollowing is a specification, referencebeing had therein to th'eaccompanying drawings.

This invention relates to printing presses, and more particularly towhat are known as platen presses, and the objects otthe invention are:first, to construct a platen-printing press which may be readilyconverted from a continuous or automatically fed press into a band ledpress: second, to embody such a construction in a horizontallyreciprocating press, in which the platen is normally in.a fixed positionand lies in the same horizontal plane with the form bed, the form bedreciprocating in a horizontal lane toward and away-from the platen; antfurther, to so improve the operating mechanism and the details ofconstruction of the machine as to improvethe operation of the machineand With these obje'ctsin view my invention consists in certain novelfeatures of construction, and in certain parts and combinationhereinafter to be described, and then more pai ticularly pointed out inthe claims.

In the accompanying drawings, Figure 1 is a side elevation of a printingpress embodying my invention; Fig. 2 is an elevation -oi the ardent themachine opposite that shown view, taken. vertically through the machine;Fig. 4. is a longitudinal sectional view, taken horizontally of themachine on the line :2 m of Fig. land looking in the direction of thebed, inking rollers and platen; Fig. 6 is an end elevation of themachine; Fig. 7 is a detail View of the operating mechanism for thepaper cutter; and Fig. 8 is a detail view of In these drawings, in whichI have shown the ,pr ess is shown as supported in a frame composed oftwo similar parallel horizontal plates 1, connected at their oppositeends by suitable transverse bars or members 2, the forward end ofthemachine being further 5 strengthened by the rods 3, located nearihetop and bottom, respectively. of the side members 1, This frame may besupported in any suitable manner, that pre'l erred consisting in thesupports or legs 4 secured to the frame at each. corner thereof.' Eachof the side members 1 is provided at its central )ortion with an opening5, having horizontal lateral edges 6 which form guideways for the slideblocks 7, which, in turn, support and actuate the combined form bed andinking drum. A horizontal movement of the reciprocation is imparted tothe slide blocks in any suitable manner, that which Iprefer being bymeans of the construction shown, in. which each slide block is shown asprovided with a pin or. trunnion 8 upon the reduced outer end of whichis j oumaled one end of a pitman 9. is journaled u on awrist pin 10eccentrically mounted on t 1e gear 11 which is secured to the outer endof a shaft 12, journaled in the side members 1 of the frame and meshingwith a pinion 13 mounted upon a shaft 14 The opposite end of the pitmanalso journaled in the side membersl of the. frame and havmg mountedthereon, preferably on the outer end thereof, beyond the pinion 13, adriving gear, such as the pulley 15 adapted to receive a-belt, bymeansof which the shaft 14 is rotatedandthe slide,

hollowed for lightness and flattened on one side thereof to constitutethe form bed. This casting is securbd to the slide block 7 by means ofscrew bolts 18, passing through the slide blocks and screwing into theends of the casting. Said casting is provided at each end with acylindrical trunnion 19, and on these trunnions are loosely mounted there voiving carriers 2.0 which supp-rt and actuate the form-inhingrollers. *ach of these carriers 's in the form of a segment of a wheelor disk of greater diameter than the inking drum, and they are given aconstant rotary motion while the press is in operation to cause them totravel around the form bed o i s and inking drum as these latterreciprocate.

To this end, each carrier 20 has connected therewith a sarocket wheel 21the sorocket cate.

wheel and carrier being preferably of a coms rocket wheels 23 aresecured to hubs or s eeves 24 on the shaft 12, in order to effect asatisfactory connection between said sprocket wheels and the shaft.tricity of the sprocket wheels is equal to the travel of the slideblocks 7, and is so arranged that the sprocket chains 22 are kept at aneven tension and the carriers 20 are rotated at an even speed as theslide blocks reci re- The form-inking rollers, indicatec by thereference numeral 25, are preferably three in number, and are supportedin the carriers 20 by having their shafts 26 extended through radialslots 27 in the carriers, which latter are provided with springs 28,mounted recesses with which the slots 27 communicate, said springsbearin on the ends of the shaft 26to press the rollers 25 radiallyinward into proper contact with the inking drum and with the type orother impression surface on the form bed. The ends of the inking drumare rabbeted or cut away, as indicated zit-29, and the form bed isprovided with transversely extending ribs or flanges 30 arranged nearthe ends thereof,

' and on the ways thus provided-travel the able manner.

the fountain 32 to the drums 17 by means of bearing rollers or wheels31Iwith which the ,form roller shafts 26 are )rovided, by means of whichthe relations 0 the rollers to the printing "and ink-distributingsurfaces are 'pro erly -maintained.

e cylindrical surface of the inking drum 17 is supplied with ink fromthe fountain 32 45 which i ocated in the forward part ofthe press and isprovided with a suitable supply roller 33 whichmay be actuated in anysuit- The ink is transferred from a ductor roller 34, having its shaft35 journaled at its opposite ends in bearing slots 36 formed in the endsof the arms 37 journaled at their opposite ends on the shaft 12 near theside-members 1 of the frame. I The shaft 38 extends between the arms 37intermediate the ends thereof, and j ournaled on the shaft 38.i s asecond arm or lever 39 having its outer end provided with an elongatedslot 40, ada ted to engage the connecting rod 3 which extends betweenthe side memhers I of the frame and to form a guide for the lever 39.The lever 39 has rigidly secured thereto, intermediate its ends, adownwardly extending member or finger 41, provided at its lower end witha roller 42 lying in The eccen- 1 during the printing operation.

the path of and adapted to be engaged by a cam 43 rigidly mounted on theshaft 12. As the shaft 12 rotates, the enlarged portion of the cam 43comes into contact with the roller 42 of the arm 41 and forces the sameupwardly, rocking the lever 39 about its pivotal connection to the rod-3and raising the outer end thereof, thereby elevating the arms 37 and theductor roller 34, which is carried thereby, and bringing the roller intoengagement with the supply roller 33 of the fountain 32. As the shaft 12continues its rotation, the roller 42 passes off the enlarged portion ofthe cam 43 and permits the lever 39 and arm 37 to move downwardly,thereby bringing the ductor roller 34 into engagement with thecylindrical surface of the inking drum 17 and supplying the same withink. Th movement of the cam 43 is so timed with relation to the movementof the slide block 7 that the ductor roller will move downwardly as theinking drum approaches the forward end of the machine. The form rollers25 are provided with suitable vibrators or reciprocating rollers 44 fordistributing the ink along the surface of the form rollers.

The vibrators44 are mounted upon shafts 45 rigidly secured to thecarriers 20, intermediate the slots 27 therein, and adapted to supportthe vibrators 44 in such a position that they will be engaged by theform rollers 25 when the same are in enga ement with the inking drum 17and have been pressed outwardly against the tension of the s wing 28,and will be out of engagement wit the form rollers when the same are inengage ment with the form.

i In connection with the horizontally reciprocating form 'bed, whichis-always maintained in a vei'tical position throughout its range ofmovement, I employ a normally fixed or stationary platen 46, located inthe path of the form bed, with the face adjacent to said form bed, whichreceives the tympan,

held firmly in vertical position, in exact pan allelism with the formbed, so that a square impression contact is always obtained, since theform bed and printing surface of the platen are always parallel witheach other The platen is rovided with a sleeve 47, by means of which itis rigidly secured to a normally stationary shaft48, which shaft issupported at its ends in the side members 1 of the frame. The impressionsurface 49 of the platen iscoextensive in length with the body portionof the casting of which it forms a part, being therefore alsocoextensive in length with the sleeve 47, and the frame members 1 arelocated close tothe end, of said casting. By 7 reason of thisconstruction, the platen is supported so close to its ends as to preventany e impression surfaces, thereby maintaining the parallelism of theplaten and form bed.

' tive arrai'igement of the reciprocating form bed and the platen,'whichis such that the form. bed is caused to reciprocate in substantially thesame, plane wit a plane extending at sul'istantially right angles to theface of the platen when the piaten is in its normal position. In thepresent instance, this )lanc is a horizontalone extending longitudlnallyof the press, as a whole, and intersecting both the form bed and theplaten. v

Vr'it-h the platen in its stationary position in the path of thel'ornrbed 16, it is adapted for use witl an Zl-lli.lii1l,l(l 'iaper feedand such a feed is herein shown, the web or roll of paper 56 being;supported beneath the press in any suit able manner, preferably by mounting the same upon arms 51, which, in turn; are mounted on the members 4at theopposite corners of the frame. The web of paper cxtends upwardlyover the impression face 46 of the platen, over a suitable guide roller52, located above said platen, and thence between the feed rollersfifi'and 54 which are intermittently driven to feed the paper forward inthe desired lerm-ths, the upper roller 54 preferably comprising aplurality of disks,

as herein shown. The means for so actuating these rollers may be of anysuitable charactor, but I prefer that herein shown which consists inextending; the shaft 54 of the lower roller 53 beyond the sup ortingframe and providing the same wit a suitable ratchet wheel 55, which isrigidly secured thereto. Journaled u. on the shaft 54", beyond theratchet whee 55, is a sleeve 56 car rying at its inner end a suitableshell or ,cas ing 57', which extends about the ratchet wheel 55 and isprovided with a springpressed pawl 58, adapted to engage the teeth ofthe ratchet 55 as the sleeve 56 is rotated forwardly and to ride overthe same on the return movement of said sleeve. The sleeve 56 carries atits outer end a sprocket wheel 59, about which extends a sprocket chain60 having one end pivotally mounted on a pin 6l-secured to an arm 62near the outer end thereof, the arm 62 being adjustably mounted u on thewrist pin 10 of one of the gears 11 T e arm 62 is preferably secured tothe wrist pin 10 by means of the usual bolt 63, and, by

oosening this bolt, the arm may-be turned about its ivotal center on thepin, thereby varying t e length of the throw thereof and correspondinglyregulating the forward movement of the ratchet wheel 55 and'roller 55;,thus. regulating the length of paper which is. fed forward at eachreciprocation of the form bed 16., The casing 57, carrying the pawl 58,is preferably returned to its normal or idle position by means of aweight 6! ar cured to the free end of the sprocket chain said platen,that. is, the line of movemcnt'of the form bed is in" 60, whichextends'over a suitable pulley 65 mounted on the'outer end of one of theconnecting rods 3 at the forward end of the ITltt-' chine. v

The paper 1s cut off into sheets by means of suitable shears whichoperate at each reciprocation of the form bed. These shears maybe of anysuitable construction, but I prefer the construction herein shown, whichconsists of a stationary blade or plate 66, having a cutting edgeadapted to cooperate with the blade 67, which is pivotally connected atone end to the supporting frame, as shown at 66, at a point beneath thelevel of the blade 66 and has its opposite end extending lutweensuitable guides 69 adapted to mov vertically the blade is movedabout its pivotal center. A rockshaft 7 0 c3- tends transversely of theframe at the rear end thereof and is journaled near its opposite ends insuitable bearing brackets 71 which are rigidly secured to the supportingframe. A projection or finger 72 is adjustably mounted on the shaft 70and is adapted to extend into asuitable guid'eway 7 ried by the blade67,and to raise and lower said b a bearings. I prefer to rock the shaft 70by means of a crank arm'74 which is rigidly sccured thereto, preferablynear one end tl1creof, and is connected at itsouter end to a slide baror red 75 having its forward end cut away or reduced, as shown, to forma shoulde-r 76 and supported on a pin or projection 77 secured to theadjacent side member 1. An arm 78 extends downwardly from the bar 75, ata point intermediate the shoulder 76 and the rear end of the ban; to apoint a short distance below the bar and thence extends in a forwarddirection substantially parallel with the bar 75.,fthus for1nin; anL-shaped arm having its shorter member secured to the bar 75, as shown,and. provided. with a slot 79 extending for substantially the fulllength of both members and corresponding in shape to the shape of thearm 78. A suitable pm or projection 80, carried by theslide block 7extends through ,the slot7 9 and serves to actuate the bar 75 and thusrock the shaft 70 about its longitudinal axis.

\Vith the slide block in its forward position, as at the beginning ofastroke, the pin 80 will be near the rear endofthe slot 7 9 and thelower edge of the bar 75 will be engaged by the pin 77 at a point in therear of the shoulder? 6. As the slide block 7 moves for ward, the 'pin80 engages thejlear wall of the vertical portion ofthe L-shaped slot 79and moves the bar 75 rearwardly throughout the remainder of the rearwardmovement of the block 7. As the block approaches the rear Ward limit ofits movement, the shoulder 76 of the bar 75 passes over the pin 77allowing 3, cardo as the rockshaft 70 is rocked in its 1 bring the pin80 into the vertical portion of the L-shaped slot 79. Thus, as the block7 begins its forward movement, the pin will engage the forward wall oftheivertical portion of said slot and carry the bar 75 toward the frontof the machine a distance sufiicient to rock the shaft and raise theblade 67. When the shaft 70 has been rocked'in such a manner, theshoulder 76 again engages the pin 77, and, riding over-the same, raisesthe bar and L-shaped member 78 a distance sufficient to bring the pin 80into th hori-} zontal portion of the Lshapedslot, th reby allowing thesame to complete its forward movement without afiecting the position ofthe bar 75. The weight of the bar .75 may be sufficient to maintain thesame in engagement with the pin 77, but I prefer to provide a sp @81which bears upon the upper edge' of t e bar and holds the loweredgethereof firmly in engagement with said,

1n. 'The feedmechanism and the cutting-off meehanism'nre preferablymounted on a separate supporting frame comprising side members 82connected by suitable transverse rods 83 and mounted upon arms 84pivotally connected to the side members 1 near their rear ends, as shownat 85, and having their forward ends sup orted upon suitable memberscarried by tie rear ortion of the main frame. Preferably, t esesupporting members consist of brackets 86 pivoted at their lower endstothe transverse members 2 of the frame, as shown at 87.

Thus, by removing the bar 75, the arms 84 and the supporting frame, withthe feed rollers and cutting-off mechanism, may be swung forwardly intothe position shown in dotted lines in Fig. 1.

When it is desired to operate the press as a hand-fed press, thesupporting frame 82 is swung forward into the position. shownin Fig. 1,and a suitable actuating member is attached to the sliding block 7 andis adapted to rack the platen and the shaft 48, upon which it ismounted, about the pivotal center and thus move the impression face 49forward y and into a position in which it is readily accessible from therear of the machine. The actuating member, bvmeans of which the platenis operated, preferably consists of an arm 88 adapted to be detachahlyeonnected at its orward end to the slide block 7 by means of a suitablepin 89, adapted to engage an aperture in the arm 88, and a hand nut 90.This arm 88 extends between suitable guides 91 and 92, preferablyconsisting of grooved rollers mounted upon pins 93 and 94, respectively,the pins 93 and 94 being mounted upon the frame member 1 and theadjacent side of the platen, respectively.

The rear end of the-arm 88 is of gradually increasing width, and,preferably, is substantially triangular, as shown at 95, and, as theslide blocks 7 move forwardly, the inclined surfaces of the triangularmember 95 are brought into engagement with the guides 91 and 92,respectively,therebyelevating the guide 92 which is carried by theplaten and moving theplaten out of the path of the form bed and into aposition in which it is readily accessible fromthe rear of the machine.'As the slide block moves rearwardly to make another impression, thewedge-shaped-mem-- her 95 is moved out from hetweenthe guides I remainstationary duringthe movement of 7 the form bed. The platen may beoperated with the guides 91 and 92 and arms 88 on either one orbothsides thereof. I have here shown these members on both sides ofthepress, as more satisfactoryresults are oh tained in this manner.

Provision is also made for moving the platenhorizontally a slightdistancefor the purpose of throwing off, the impression when necessary.To this end, the shaft 48 terminates at its ends in reduced'bearingtrunnions 96, each of said trumiions rotating in a horizontally slidingcross-head or box 97,

mounted in a rectangular aperture 98, so that the lateral horizontalsides 99 of said aperture constitute guideways for said head,

which is of less width than said'aperture so, that it maybe movedhorizontally thereinl.

In front of the cross-head 97 is located, in the aperture 98, a slidingbox of a width equal to the-width of the aperture 98, so that thevertical margins .101 of said aperture constitute guide margins for saidplate or box which is of less width than the aperture 98 so that it iscapable of sliding vertically therein.

Within the box 100 there is mounted to, r0- tate a sleeve 102,'in whichthe correspondingv trunnion 96 of the shaft 48 is eccentrically mounted.seenthat when the sleeves 102 are rotatedin their boxes 100, the shaft48 will be movedv From this construction, it will-be 1 horizontally, thearrangement ofthe guide plates being such as to maintain the axis ofsaid shaft always in the same horizontal plane throughout its range ofmovement, thereby preventing lateral displacement of the platen. 102 tobe readily operated simultaneously, said sleeves are provided on theirprojecting ends "with arms 103, which are connected bv In order toperm1t.the sleeves.

links 104 and arms 105 projecting from the i 7 rock-shaft 106, extendingtransversely of the machine near the end thereof and controlled. by ahand. lever 107. This rock-shaft takes the place of oneof the tie rods 3of the frame.

I e operation of the press will be obvious from the description of theoperation of the several parts thereof, and it will be apparent that Ihave provided a press which is -adapted to be used with a continuous orautomatic feed, and, when so used, the platen will bein perfectparallelism with the form bed and will remain in that position, thusgiving a uniform impression; which is adapted to be em loyed as a handpress, the automatic fee mechanism being uncoupled and moved out of theway, and the operating mechanism of the platen being connected to theslide block carrying the form bed, whereby, the platen is moved out ofthe path of the form bed during the return stroke thereof and is movedinto a position in which the sheet may be fed. thereto by hand; furtherthat I have embodied such a convertible ress in a horizontal frame, inwhich the p aten and form bed are normally in the same horizon' I talplane, the form bed reciprocating in a horizontal ilane toward and awayfrom the platen; an further, it will be apparent that I have improvedthe detail construction and arrangement of the parts so as'to secure anim roved operation 'of the press as a whole an to render the same moreaccurate in its operation.

I wish it to be understood that I do not desire to be limited to theexact details of ,construction shown and described, for obvi mounted onsaid frame and adapted to re eiprocate toward and away from said platen,actuating mechanism for moving said platen into and out of the path ofsaid form bed, said actuating mechanism being adapted to be renderedinoperative, and automatic feed mechanism movably mounted on said frame.
